To all whom t may concern:

Be it known that I, RUDOLPH W. GOEB, a citizen of the United States,residing at St. Louis, Missouri, have invented a certain new and usefulImprovement in Measuring-Valve Mechanisms, of which the following is afull, clear, and eXact description, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, forming part of thisspecilication, in which.

Figure 1 is avertical sectional view through my improved measuring-valvemechanism. Fig. 2 is a sectional view on the line 2 2 of Fig. 1. Fig. 3is a top plan view; and Fig. 4 is a rear elevational view, partly insection.

This invention relates to a new and useful improvement inmeasuring-valve mechanisms, the object being to provide means foradjusting the telescoping cylinders forming the measuring-chamber,whereby the cubical contents thereof may be regulated, and also toprovide means whereby the valves which coperate with the outer ends ofthe telescoping sections may be adjusted so as to be seated at theproper time with relation to each other.

With these objects in view the invention consists in the construction,arrangement, and combination of the several parts, all as will beherinafter described and afterward pointed out in the claims.

My improved measuring-valve mechanism is designed particularly for usein connection with the machine for making pulp Stoppers shown in anapplication liled by me'on Jane uary 19,1905, and seriallynumbered241,865. The fluid to be measured is pulp-water-that is, water havingabout two grains of pulp per cubic inch of water-although it is obviousthat the present construction is applicable to other kinds of lluid.

In the drawings, 1 indicates the tank .containing the fluid to bemeasured, and 2 indicates a trough arranged under the tankfor conductingoff the fluid after it has been measured and issues from themeasuringchamber.

3 indicates a cylinder screwed into the bottom of the tank and having aseat at its upper edge, with which seat coperates a valve 4, having,preferably, a rubber facing 4a for coperating with the valve-seat. Valve4 is provided with an interiorly-threaded stem 5, which is provided witha longitudinal rib 5a on its side, (see Fig. 2,) which rib coperateswith a spider 6, secured in the cylinder 3. By this construction thevalve-steinv is slidable longitudinally in the spider, but is preventedfrom rotation.

7 indicates a hollow cap arranged on the upper end of valve 4 forinclosing the upper threaded end of the operating-rod 8 and eX- cludingthe pulp-water therefrom. Rod 8 has threaded engagement with the valve4. The lower end of rod 8 passes through a sleeve 9, which sleevecarries a valve 10 at ,its upper end, said valve 10 having a facing ofrubber 10a coperating with the seat on the lower end of a cylinder 11,said cylinder 11 having a sliding engagement with the cylinder 3, aswill berhereinaftcr described. The lower end of sleeve 9 is providedwith lateral lianges 9a, forming a head. .Sleeve 9 is also slottedlongitudinally, as at 9b, which slots receive and coperate with across-pin 12, carried by a rod 13. The lower end of rod 13 has athreaded engagement with a coupling-block 14, which. is pivotallTmounted upon an operating-lever 15. Lever 15 is vibrated, having adefinite stroke; but it is 0bvious that instead of the motive power foractuating the rod 13 being in the form of a lever it could be in adifferent form.

Rod 8, which passes through the sleeve 9, is made hollow at its lowerend to receive the rod 13 and its cross-key 12, said cross-key passingthrough slots .8a in the lower end of the rod 8. The lower end of rod 8terminates in llanges 8b, on which is seated a spring 16, said springbearing at its upper end against the flange 9a. The energy of thisspring is directed at all times to movethe valves 4 and 10 toward eachother-that is, rod 8 carries valve 4 and actuation of the' spring is tomove these parts downwardly while sleeve 9 and its valve 10 are pressedupwardly.

In the position of the parts shown in Fig. 1 it will be seen that thecross-key 12 is located in the lower end of slot 9b and in the upper endof slot Su. If lever 15 is moved upwardly, the cross-key will lift therod 8 and valve 4 so as to admit the fluid in tank 1 into the chamberformed by the cylinders 3 and 11. In this movement the flange 8a IOCicompresses the spring 16 and more firmly seats the valve 10, thecross-key riding up in the slot 9b and not disturbing the position ofsaid valve 10. As lever 15 descends the spring forces the valve 4downwardly onto its seat until the cross-key reaches the position shownin Fig. 1, in which both valves are seated, the continued downwardmovement of lever 15 causing the cross-key 12 to engage the sleeve 9 andmove valve 10 away from its seat. This unseating of valve 10 enables thecontents of the measuring-chamber to be discharged into the trough 2,and also the flange 9a compresses the s ring 16 and causes the valve 4to more firm y seat itself while the valve 10 is open. This operation ofthe valves in being alternately seated and unseated enables the fluid intank 1 to fill the chamber at each elevation of valve 4, and thecontents in the chamber are then discharged when valve 10 is open, valve4 being seated just previous to the opening of valve 10 and valve 10likewise being seated just previous to the opening of valve 4.

In order to regulate the cubical contents of the measuring-chamber, thecylinders 3 and 11 have telescopic engagement with each other, thecylinder 3, as before described, being threaded into the lower end oftank 1. Cylinder 11, as shown in Figs. 3 and 4, is supported by brackets17, which brackets extend laterally through slots in the side walls ofthe trough 2. These brackets have threaded openings in their ends,through which pass the threaded portions of rods 18. These rods areprovided with knurled handwheels on their lower ends. Rods 18 passthrough perforated lugs or ears 20, secured to the bottom of trough 2,in which said rods are free to turn, collars being pinned on the rod toprevent longitudinal movement thereof, but permitting free rotation ofthe rod.

In order to adjust the cylinders with respect to each other, the rods 18are rotated and by reason of the threaded engagement with the bracket 17will effect a vertical movement of cylinder 11, and thus increase orreduce the cubical capacity of the measuring-chamber. The adjustment ofthe cylinder 11 will of course change the relation of the valves to thecylinders, and in order to reestablish the proper relation between thevalves and their seats I first loosen a jam-nut 14, which locks the rod13 in the coupling 14, and then rotate the rod 8 and sleeve 9, whicheffects a changed relation between the valves. Thus if the cylinder 11was moved up a short distance to reduce the cubical capacity of themeasuring-chamber it will be obvious that when the lever 15 is in itscentral position the valve 10 will be held ofi' of its seat. By rotatingthe rod 13 in its coupling 14-say to the right-the cross-pin 12 will beelevated, permitting the sleeve 9 and its valve 10 to be raised upwardlyby the spring 16. The same motion causes the rod 8 through its threadedengagement with the valve 4 to maintain the established relation betweensaid valve 4 and the rod 13, the threads on rods 8 and 13 having thesame pitch. The threaded connection between rod 8 and valve 4 is not forthe purpose of adjusting the position of said valve, because the seatwith which it coperates is stationary, said threaded connection beingused only for compensating purposes.

Should the cylinder 11 be moved downwardly to increase the cubicalcapacity of the measuring-chamber, it is obvious that the reverse of theoperation above described will be necessary. The operator can determinethe seating positions of the valves by observing the position of the key12 in the slots 8a and 9b.

I am aware that minor changes in the construction, arrangement, andcombination of the several parts of my device can be made andsubstituted for those herein shown and described without in the leastdeparting from the nature and principle of my invention.
